When performing cut boundary interpolation I'm getting cbdo file in which only some nodes have 3 displacements (UX, UY, UZ) - most of them have only UX & UZ.
Why is it happening? Is this correct? Could someone help me with this?
Have built a model of pressure vessel supported on skirt.
Loads are internal pressure and forces on nozzles.
Bottom of skirt is fixed (all DOF=0).
When trying run analysis an error DOF LIMIT EXCEEDED appears and program terminates.
What to do to fix the problem?
